System and method for demonstrating a path of a projectile

Abstract

A system for demonstrating a path of a projectile comprises a flexible wire, a first attachment device connected to a first end of the flexible wire, a second attachment device connected to a second end of the flexible wire, a coupling assembly comprising a trajectory rod attachment device configured to attach to a trajectory rod and a wire attachment device movably connected to the trajectory rod attachment device and configured to attach to the flexible wire.

What is claimed is: 
     
       1. A system for demonstrating a path of a projectile, comprising:
 a flexible wire; 
 a first attachment device connected to a first end of the flexible wire; 
 a second attachment device connected to a second end of the flexible wire; and 
 a coupling assembly comprising a trajectory rod attachment device configured to attach to a trajectory rod and a wire attachment device movably connected to the trajectory rod attachment device and configured to attach to the flexible wire. 
 
     
     
       2. The system as claimed in  claim 1 , wherein the coupling assembly comprises a ball and socket, wherein the wire attachment device is rotatably movable relative to the trajectory rod attachment device. 
     
     
       3. The system as claimed in  claim 1 , wherein the wire attachment device comprises a threaded screw and a threaded hole configured so that the wire attachment device grips the flexible wire by tightening the threaded screw. 
     
     
       4. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device is removably connected to the flexible wire. 
     
     
       5. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device is removably connected to the flexible wire via a male threaded portion mated to a female threaded portion. 
     
     
       6. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device comprises a suction cup. 
     
     
       7. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device comprises a clamp. 
     
     
       8. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device comprises a magnet. 
     
     
       9. The system as claimed in  claim 1 , wherein at least one of the first attachment device and the second attachment device comprises a substantially flat surface having a plurality of holes and configured for attachment to a surface via screws passing through the plurality of holes. 
     
     
       10. The system as claimed in  claim 1 , wherein the first attachment device and the second attachment device comprise different elements from a set consisting of: a suction cup, a clamp, a magnet, and a substantially flat surface having a plurality of holes and configured for attachment to a surface via screws passing through the plurality of holes. 
     
     
       11. The system as claimed in  claim 1 , further comprising the trajectory rod. 
     
     
       12. A method for demonstrating a path of a projectile, comprising:
 providing the system as claimed in  claim 1 ; 
 providing a trajectory rod; 
 identifying a first point in the path of the projectile; 
 identifying a second point in the path of the projectile; 
 attaching the first attachment device to a first region; 
 bending the flexible wire; 
 attaching the second attachment device to a second region; 
 placing the trajectory rod through the first and second points; 
 attaching the wire attachment device to the flexible wire; and 
 attaching the trajectory rod attachment device to the trajectory rod so that the trajectory rod is substantially parallel with a line passing through the first and second points. 
 
     
     
       13. The method as claimed in  claim 12 , wherein the coupling assembly comprises a ball and socket, wherein the wire attachment device is rotatably movable relative to the trajectory rod attachment device, and wherein the method further comprises adjusting the trajectory rod attachment device relative to the wire attachment device. 
     
     
       14. The method as claimed in  claim 12 , wherein the first attachment device is removably connected to the first end, and wherein the method further comprises removing the first attachment device and attaching a third attachment device to the first end. 
     
     
       15. The method as claimed in  claim 14 , wherein the first attachment device comprises a magnet and the third attachment device comprises a suction cup.
